Hi, all, I am a 45-year-old female and was diagnosed as PE in September this year and since then I have been on Eliquis. They didn't find any clots in my legs when I was in the hospital. I was told that I had unprovoked PE. My doctor ordered some genetic tests 30 days after my PE and my labs showed that everything is normal except a low protein S Ag-free (16%). After searching some information online, I think that I have PSD. But my hematologist told me that my labs are not diagnostic of PSD and he will repeat the test after I stop taking Eliquis for a while. But I got some information online saying that Eliquis does not affect protein S levels. Does anyone have similar situation?
